Do these newer FRN sheaths dull the knives on the insert/draw? I used to own a Rock Salt and my brother has a few Aquas that have this problem. Thanks.
In the old days of leather sheaths, the two sides of the sheath were separated by a welt of thicker leather that protected the stitching from being cut by the blade's edge. Since leather is soft, if the edge contacted it on the blade's way in or out of the sheath, the effect was negligible.
Most molded Kydex sheaths are two-piece or foldover construction with the seam on the edge side. They don't have a welt and even if you try, it's difficult to get the edge all the way into the crease of the seam to dull it.
Molded polymer sheaths combine the inner cavity of the welt-style construction with a material that is much harder than leather. If you draw your knife and drag the edge along the inside of the sheath, you will dull the edge. The key to NOT doing this is to use proper technique, which is to consciously index the spine of the blade on the inside of the sheath and ride it in while maintaining pressure with the spine.
For the record, this applies to all polymer sheaths, regardless of manufacturer, as well as traditional wooden sheaths and scabbards.
I hope this helps.
